Anyone have an early 1958 430 water pump core? My 1958 Continental's was replaced at some point with a 1959 casting for an A/C car. Looking to go back to the correct casting for non-A/C. From what I've been told, the correct casting # should be CA-EDF-8505-A. Preferable date code is July-Sept 1957 (7-7-X to 7-9-X). Thanks, Scott
